Using the Jet 505902 air hammer is quite straightforward. First, connect the air hose to the air inlet and make sure it's properly secured. Then, adjust the air pressure to 90 PSI. When starting the tool, use the variable - speed trigger on the pistol grip to control the impact gently. You can use the included 4 - piece chisel set for different jobs by quickly changing the tools with the standard spring retainer. While using the air hammer, be aware of the noise level of 112 DB, so it's a good idea to wear ear protection. Also, the vibration value is 11.8 M/S2, so try to hold the tool firmly. For maintenance, regularly check the air hose for any damages and make sure the connections are tight. Keep the tool clean after each use to ensure its long - term durability. And remember, this tool is built to handle 6 - hour workdays, but giving it a break from time to time can also extend its lifespan.
